通过预处理改善地震记录品质和提高分辨率

IMPROVING SEISMIC RECORD QUALITY AND RESOLUTION WITH PREPROCESSING

组合检波对提高记录品质的作用是毋庸置疑的。但是在地形条件恶劣的地区，组合检波的效应会降低，特别是大基距组合会使高频信号畸变。为充分发挥多道仪器采集的优越性，在组合之前，通过现场预处理克服组内检波器之间的微静校正和微动校正时差，从而达到改善记录品质和提高分辨率的目的。

The seismic record quality can be improved with geophone array, but it performs unsatisfactorily in bad topographic conditions, especially long-distance geophone array make high-frequency signal distort. To realize the superiority of multitrace collection, field preprocessing should be made to overcome micro-static moveout correction and ndcro normal moveout correchon and then to improve seisndc record quality and resolution.
